Types of Corona Viruses and Their Symptoms

  • Coronaviruses are a large family of single-stranded RNA viruses that cause diseases in animals and humans.
  • In humans, the viruses usually cause mild to moderate upper-respiratory tract illnesses such as the common cold.
  • In the last two decades, more aggressive coronaviruses have emerged that are capable of causing serious illness and even death in humans.
  • In which three significant are
  1. SARS-CoV: 2003 in China (animal source not yet known, bats thought to have given it to other animals, probably civet cats)
  2. MERS: 2012 in Saudi Arabia (transmitted by dromedary camels)
  3. SARS-CoV-2: 2019 in Wuhan (source not yet known, possibly bats)
  • Classification - Coronavirinae are one of the two subfamilies of Coronaviridea, with the other being Torovirinae.
  • Coronavirinae can be further subdivided into alpha, beta, gamma and delta coronaviruses.
  • While coronaviruses from all four categories can be found in mammals, bat coronaviruses are the likely gene source of alpha and beta coronaviruses, while avian coronaviruses are the probable gene sources of gamma and delta coronaviruses.
  • While there are hundreds of coronaviruses, there are seven that we know can infect humans.
  • Out of the seven, two are alpha coronaviruses (229E and NL63) and four are beta coronaviruses (OC43, HKU1, MERS and SARS-CoV).
  • The classification of the viruses is based on their phylogeny, which is to say it reflects how these virus strains evolved from their common ancestors.
  • Symptoms - Before SARS-CoV-2 and MERS, SARS-CoV was the first example of a human coronavirus that could cause serious illness in humans in the form of severe acute respiratory syndrome.
  • Other human coronaviruses such as OC43 and 229E are known to cause the common cold, whereas NL63 is associated with serious respiratory symptoms such as upper respiratory tract infection and pneumonia.
  • NL63 is primarily associated with infections among children, it has also been detected in immuno-compromised adults with respiratory tract infections, OC43 can also cause gastroenteritis.
  • Symptoms of SARS include cough, shortness of breath, diarrhea. In severe cases, the symptoms can progress to respiratory distress, which may require intensive care.
  • MERS symptoms include fever, cough and shortness of breath.
  • Further, while SARS-CoV-2 is considered to be milder than SARS-CoV and MERS, it is especially difficult to control its outbreak, given its high infectiousness.

  • The town’s religious centre was founded by a 7th-century Hindu Pallava King—Narasimhavarman, also known as Mamalla—for whom the town was named.
  • It contains many surviving 7th- and 8th-century Pallava temples and monuments, chief of which are the sculptured rock relief popularly known as “Arjuna’s Penance,” or “Descent of the Ganges,” a series of sculptured cave temples, and a Shiva temple on the seashore.
  • The town’s Five Rathas, or monolithic temples, are the remnants of seven temples, for which the town was known as Seven Pagodas. The entire assemblage collectively was designated a UNESCO World Heritage Site in 1984.

Humayun’s Tomb

  • Humayun's tomb is the tomb of the Mughal Emperor Humayun in Delhi, India.

  • It is the first garden-tomb on the Indian subcontinent.
  • It represented a leap in Mughal architecture, and together with its accomplished Charbagh garden, typical of Persian gardens, but never seen before in India, it set a precedent for subsequent Mughal architecture.

Edakkal Caves

  • Edakkal Caves also Edakal, are two natural caves at Edakkal, around 120 km south-west of Mysuru, in Wayanad district of Kerala.
  • The caves are situated 1,200 m (3,900 ft) above sea level on Ambukuthi Mala, on the Mysore Plateau, in the Western Ghats.
  • The Edakkal caves are believed to be camping shelters of the Neolithic community (the south Indian Neolithic culture zone).
  • The cave walls contain a collection of Neolithic rock engravings and images (which were incised over a period of time).
  • The major part of images on the cave walls may belong to late Neolithic period (i. e., first millennium BC).
  • With the exception of Edakkal, no concrete evidence for the existence of a true Neolithic culture in Kerala has so far been discovered.
  • The caverns at Edakkal are not technically caves, but rather a cleft, rift or rock shelter, fissure caused by a piece of rock splitting away from the main body.
  • On one side of the cleft is a rock weighing several tons that covers the cleft to form the "roof" of the cave.
  • Recently a huge crack has developed on the eastern part of Ambukuthi hills, on which the Edakkal caves are situated.
  • The crack was exposed after a fire devastated the area a few days ago.
  • The crack had formed along a 60 m stretch on the hill slope, the exact cause could be ascertained only after a study by experts.
  • The crack would not lead to a landslip during moderate rain, but the possibility of landslips in the area during heavy rain could not be ruled out.
